Does Altitude affect boost pressure?
I ran (Drag raced) at a track at 600 feet above sea level (Toronto), then I went to a track at 2200 feet above sea level (Edmonton) and I didn't change a thing on the car. Yet I am showing 3-4 less pounds of boost at the higher elevation. I never changed anything on the car from one track to the other. I am using Big stuff 3 and noticed quite a difference in boost between the 2 elevations. If not altatude then what would affect boost pressure?
